Fault Possible cause
ERR on status line
(communications error)
No power to Sensor
No communications to Sensor
Check connections to sensor. Check for 12 V
between YELLOW wire and its BLACK pair

Always set the ‘Display Mode’ to “Master” in
single display systems.
Two or more master displays connected to a

ICS NAV6hub faultfinding
The ICS NAV6hub is provided with 3 status LEDs. The one marked ‘POWER’ on
the pcb should always be lit when power is applied to the ICS NAV6hub.
The other 2 LEDs indicate the status of communications on the 2 RS485 ports.
Each LED is only ON when a unit (display or sensor) is talking on the other port.
The only units that ‘talk’ are sensors and the ‘master’ display. The units talk 4
times per second for a very short period each time. Thus the LEDs appear to flash
ON for a short time.
